改进nsga2多目标优化

说明：  一个经典的宽带多位sigma delta调制器设计，较为好用(More than a classic sigma delta modulator broadband design, the more useful)

说明：  做实验的一些心得体会，愿大家有所受益很好，欢迎大家学习，交流！(verygood！let we see！verygood！let we see！verygood！let we see！verygood！let we see！verygood！let we see！)

基于前馈补偿的PID控制算法。可以通过设置M参数查看控制效果（M=2时误差平稳且接近0）。(Feedforward compensation based on the PID control algorithm. You can view the control parameters by setting the effect of M (M = 2 when the error is stable and close to 0).)

小波分析是目前数学中一个迅速发展的新领网域，它同时具有理论深刻和应用十分广泛的双重意义。信号处理的目的就是：准确的分析、诊断、编码压缩和量化、快速传递或存储、精确地重构（或恢复）。(Wavelet analysis is a rapidly developing new collar domain in mathematics, which has both theoretical significance and profound and extensive application. The purpose of signal processing is: accurate rapid analysis, diagnosis, coding and quantization, transmission or storage, accurate reconstruction (or recovery).)
